计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
1、x^2+10x+21=02、x^2-x-1=03、3x^2+6x-4=04、3x(x+1)=3x+35、4x^2-4x+1=x^2+6x+96、7x^2-√6x-5=0
解下列方程!就三道!解下列方程.1、x/x-2 - 1-x²/x²-5x = 2x/x-3(x/x-2 - 1-x²不是一起的!)2、5x/x²+x-6 - 5-2x/x²-x-12=7x-10/x²-6x+8(5x/x²+x-6 - 5-2x不是一起的!)3、x-4/x-5 + x-8/x-9=x-7/x-
3(3x-2)=10-0.5(x+3.5)35(x-2)-15(5x-6)=(22x-63)-21(3x-4)
(35 -5x)/10
解方程.(5x/x²+x-6)+(2x-5/x²-x-12)=7x-10/x²-6x+8
(x-3)(x+4)-2(x+5)(x-5),其中x-10先化简再求值
3(x-12+23=35 7x-8=2x+27 5x-18=3-2x 3(2x-1)+10=37 3(x+2)*5=(x+2)
(2x-2)(x-1)=0 x(x-5)=5x-10
x+x÷5+(x+35)=112
=(x^2-5x+4)(x^2-5x+6) =(x^2-5x)^2+10(x^2-5x)+24 是怎么转化的(X-1)(X-2)(X-3)(X-4) =(X-1)(X-4) (X-2)(X-3)=(x^2-5x+4)(x^2-5x+6)=(x^2-5x)^2+10(x^2-5x)+24=x^4-10x^3+25x^2+10x^2-50x+24=x^4-10x^3+35x^2-50x+24不好意思我弄错了,是=(x^2-5
=(x^2-5x)^2+10(x^2-5x)+24 =x^4-10x^3+25x^2+10x^2-50x+24 这是怎么转化的(X-1)(X-2)(X-3)(X-4) =(X-1)(X-4) (X-2)(X-3)=(x^2-5x+4)(x^2-5x+6)=(x^2-5x)^2+10(x^2-5x)+24=x^4-10x^3+25x^2+10x^2-50x+24=x^4-10x^3+35x^2-50x+24
5x-35≥6x-10
(5-X)X(7-X)=35 和(5+X)X(7+X)=35
5x+(15-x)=35
为什么3X-2(-X?(X-1)+5)=-3X +2 X? (X-1)-10
解方程 x(2x-5)=4x-10 x+5x+7=3x+11
3X=5×(X-10)
